Overview of water well drilling rigs

In the 2nd century BC, China has used manpower and used bamboo bow elastic force to make the cone drill bit impact the ground to drill. Later, it was used in rural China for a long time. It was not until the 1950s that wire rope percussion drilling rigs were introduced from abroad. In the early 1960s, simple water well drilling rigs such as large and small pot cones and punch-grab cones were developed. Around 1966, the positive circulation rotary drilling rig began to be developed, the reverse circulation rotary drilling rig and the compound drilling rig were successfully developed around 1974, and the down-the-hole vibrating rotary drilling rig was created in the late 1970s. European and American countries mainly used wire rope percussion drilling rigs in the 19th century. In the 1860s, France first used rotary rotary drilling rigs, which were later introduced to the United States and developed rapidly. In the 1950s, the development of reverse-circulation rotary rotary drilling rigs began. Later, rotary rotary drilling rigs using compressed air instead of mud as the well washing medium appeared. In the 1970s, hydraulic power head rotary drilling rigs were developed.
